disciplined-implementation
Phase 3 of disciplined development. Executes approved implementation plans step by step. Each step includes tests, follows the design exactly, and produces reviewable commits.
neuropixels-analysis
Neuropixels neural recording analysis. Load SpikeGLX/OpenEphys data, preprocess, motion correction, Kilosort4 spike sorting, quality metrics, Allen/IBL curation, AI-assisted visual analysis, for Neuropixels 1.0/2.0 extracellular electrophysiology. Use when working with neural recordings, spike sorting, extracellular electrophysiology, or when the user mentions Neuropixels, SpikeGLX, Open Ephys, Kilosort, quality metrics, or unit curation.
dsp-filter-designer
Design and test DSP filters (highpass, lowpass, bandpass, notch) for WaveCap-SDR. Use when adding filters to demodulation pipeline, debugging filter response, or tuning cutoff frequencies and rolloff characteristics.

Imported from https://github.com/terraphim/opencode-skills.
canvas-design
Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
codex-peer-review
A Claude Code skill that leverages OpenAI's Codex CLI to provide AI-powered peer review, second opinions on architecture/design decisions, implementation validation, and security analysis for high-stakes development scenarios.
gemini-peer-review
This skill enables Claude Code to collaborate with Google's Gemini AI via CLI for peer review, providing second opinions on architecture, security, and design decisions, especially for large codebases.
ui-ux-design
Standard Operating Procedure for design workflow. Phase 1: Variations (diverge), Phase 2: Functional (converge), Phase 3: Polish (systemize).
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
ue
UE (user experience engineering) skill for defining end-to-end user experience behavior and interaction logic. Use for tasks like flow design, interaction models, state machines, error recovery, input validation, usability heuristics, accessibility, and turning UX intent into testable acceptance criteria for implementation.
ui
UI/UE (user interface & user experience) skill for designing and reviewing interfaces. Use for tasks like creating UI specs, interaction states, component guidelines, visual hierarchy, responsive layouts, accessibility, design tokens, and handoff-ready requirements for engineers.
tool-use
Tool use patterns for Claude including schema design, tool_choice modes, result handling, parallel execution, error recovery, and extended thinking integration.
definition-resource-design
Guide for designing Definition resources in OptAIC (the "Law"). Use when creating PipelineDef, StoreDef, AccessorDef, OpDef, MLModuleDef, or PortfolioOptimizerDef. Covers interface_spec, input/output schemas, compatibility rules, and embedded guardrail contracts.
task-execution-engine
Execute implementation tasks from design documents using markdown checkboxes. Use when (1) implementing features from feature-design-assistant output, (2) resuming interrupted work, (3) batch executing tasks. Triggers on 'start implementation', 'run tasks', 'resume'.
jn
Use JN for data transformation and ETL. Read data with 'jn cat', filter with 'jn filter', write with 'jn put'. Convert between CSV/JSON/Excel/YAML formats. Stream data through Unix pipes. Integrate with VisiData for visual exploration. Use when working with data files, format conversion, filtering data, or ETL pipelines.
task-execution-engine
Execute implementation tasks from design documents using markdown checkboxes. Use when (1) implementing features from feature-design-assistant output, (2) resuming interrupted work, (3) batch executing tasks. Triggers on 'start implementation', 'run tasks', 'resume'.
frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications, OR when they provide screenshots/images/designs to replicate or draw inspiration from. For screenshot inputs, extracts design guidelines first using ai-multimodal analysis, then implements code following those guidelines. Generates creative, polished code that avoids generic AI aesthetics.
responsive-design
Imported from https://github.com/iButters/ClaudeCodePlugins.
aesthetic
Create aesthetically beautiful interfaces following proven design principles. Use when building UI/UX, analyzing designs from inspiration sites, generating design images with ai-multimodal, implementing visual hierarchy and color theory, adding micro-interactions, or creating design documentation. Includes workflows for capturing and analyzing inspiration screenshots with chrome-devtools and ai-multimodal, iterative design image generation until aesthetic standards are met, and comprehensive design system guidance covering BEAUTIFUL (aesthetic principles), RIGHT (functionality/accessibility), SATISFYING (micro-interactions), and PEAK (storytelling) stages. Integrates with chrome-devtools, ai-multimodal, media-processing, ui-styling, and web-frameworks skills.
thought-experiments
Design, analyze, and evaluate philosophical thought experiments. Use when: creating new thought experiments to probe specific intuitions, analyzing existing thought experiments for hidden assumptions, generating variants that isolate different variables, stress-testing philosophical positions through scenarios, exploring edge cases. Triggers: 'thought experiment', 'imagine', 'suppose', 'hypothetical', 'what if scenario', 'intuition pump', 'trolley problem', 'zombie', 'Mary's room', 'Chinese room', 'experience machine', 'teletransportation', 'original position', 'veil of ignorance', 'Gettier case'.
slidev-drawings
Draw and annotate during Slidev presentations. Use this skill for live annotations, highlighting, and visual explanations.
fontend-design
Imported from https://github.com/ghealysr/nicole-assistant.
ui-freeze
Protects design and theme files from unintended changes. Locks tailwind.config, global CSS, and theme variables. Requires explicit confirmation before modifying UI components. Activate on changes to CSS, theme config, or layout components.
ux-evaluator
This skill should be used when evaluating UI components against UX best practices. Use for reviewing buttons, navigation elements, spacing, visual hierarchy, or any interface element. Provides a systematic 3-dimension framework (Position, Visual Weight, Spacing) aligned with industry standards (Balsamiq, Nielsen heuristics). Invoke when user asks to "review UX", "check button design", "evaluate layout", or references design guidelines.
